ofxAssimpModelLoader not compiling

I’m trying to use 3d models, so i want a project with ofxAssimpModelLoader.
Unfortunately, the project wont build at all. I tried simply making a new project with the addon, and it won’t build even before I touch anything . I get several “unresolved external symbol” errors. I tried adding assimp.lib in the linker options, but then I simply get “cannot open assimp.lib”.

So i figured out it works if i create the project with the project generator instaed of the plugin… still don’t know why though.
